This episode of NOVA scienceNOW introduces renowned paleontologist George Poinar, whose study of extinct creatures preserved in amber partly inspired Jurassic Park; examines the northern lights and "space weather"; studies mice that Ron Evans and his team genetically altered for heightened endurance; and profiles Franklin Chang-Diaz, designer of a revolutionary new rocket that could power a new generation of space explorers.

Very inspiring. The article on endurance, the rising of Diaz from 3rd world country to astronaut to working with plasma rockets as well as the quest to predict earthly weather with information with solar weather data (NASA's Themis project) is very exciting.
